- © 2019 Institute of Physics Publishing. All rights reserved. Within the EUROfusion MST1 work package, a series of experiments has been conducted on AUG and TCV devices to disentangle the role of plasma fueling and plasma shape for the onset of small ELM regimes. On both devices, small ELM regimes with high confinement are achieved if and only if two conditions are fulfilled at the same time. Firstly, the plasma density at the separatrix must be large enough (ne,sep/nG ∼ 0.3), leading to a pressure profile flattening at the separatrix, which stabilizes type-I ELMs. Secondly, the magnetic configuration has to be close to a double null (DN), leading to a reduction of the magnetic shear in the extreme vicinity of the separatrix. As a consequence, its stabilizing effect on ballooning modes is weakened.

- The research program of the TCV tokamak ranges from conventional to advanced-tokamak scenarios and alternative divertor configurations, to exploratory plasmas driven by theoretical insight, exploiting the device's unique shaping capabilities. Disruption avoidance by real-time locked mode prevention or unlocking with electron-cyclotron resonance heating (ECRH) was thoroughly documented, using magnetic and radiation triggers. Runaway generation with high-Z noble-gas injection and runaway dissipation by subsequent Ne or Ar injection were studied for model validation. The new 1 MW neutral beam injector has expanded the parameter range, now encompassing ELMy H-modes in an ITER-like shape and nearly non-inductive H-mode discharges sustained by electron cyclotron and neutral beam current drive. In the H-mode, the pedestal pressure increases modestly with nitrogen seeding while fueling moves the density pedestal outwards, but the plasma stored energy is largely uncorrelated to either seeding or fueling. High fueling at high triangularity is key to accessing the attractive small edge-localized mode (type-II) regime. Turbulence is reduced in the core at negative triangularity, consistent with increased confinement and in accord with global gyrokinetic simulations. The geodesic acoustic mode, possibly coupled with avalanche events, has been linked with particle flow to the wall in diverted plasmas. Detachment, scrape-off layer transport, and turbulence were studied in L- and H-modes in both standard and alternative configurations (snowflake, super-X, and beyond). The detachment process is caused by power 'starvation' reducing the ionization source, with volume recombination playing only a minor role. Partial detachment in the H-mode is obtained with impurity seeding and has shown little dependence on flux expansion in standard single-null geometry. In the attached L-mode phase, increasing the outer connection length reduces the in-out heat-flow asymmetry. A doublet plasma, featuring an internal X-point, was achieved successfully, and a transport barrier was observed in the mantle just outside the internal separatrix. In the near future variable-configuration baffles and possibly divertor pumping will be introduced to investigate the effect of divertor closure on exhaust and performance, and 3.5 MW ECRH and 1 MW neutral beam injection heating will be added.

World Federation of Societies of Biological Psychiatry (WFSBP) Guidelines for Biological Treatment of Schizophrenia : Part 1: Update 2012 on the acute treatment of schizophrenia and the management of treatment resistance.

Tidskriftsartikel (refereegranskat)abstract
- These updated guidelines are based on a first edition of the World Federation of Societies of Biological Psychiatry Guidelines for Biological Treatment of Schizophrenia published in 2005. For this 2012 revision, all available publications pertaining to the biological treatment of schizophrenia were reviewed systematically to allow for an evidence-based update. These guidelines provide evidence-based practice recommendations that are clinically and scientifically meaningful and these guidelines are intended to be used by all physicians diagnosing and treating people suffering from schizophrenia. Based on the first version of these guidelines, a systematic review of the MEDLINE/PUBMED database and the Cochrane Library, in addition to data extraction from national treatment guidelines, has been performed for this update. The identified literature was evaluated with respect to the strength of evidence for its efficacy and then categorised into six levels of evidence (A–F; Bandelow et al. 2008b, World J Biol Psychiatry 9:242). This first part of the updated guidelines covers the general descriptions of antipsychotics and their side effects, the biological treatment of acute schizophrenia and the management of treatment-resistant schizophrenia.

Stigma in midsize European countries

Ingår i: The Stigma of Mental Illness - End of the Story? Gaebel W., Rössler W., Sartorius N. (eds.). - Cham : Springer. - 9783319278391 ; , s. 417-432

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter presents reports from ten mid-size European countries. Authors from Austria, Croatia, Norway, Poland, Portugal, Romania, Sweden, Slovakia, Slovenia and Turkey report about the situation in their countries. In all countries, various activities have been performed in order to fight against stigma. These included national and local campaigns, as well focussed programmes for pupils, students and other groups of the population. The content of the campaigns showed a broad range. While some included all types of mental disorders, other focussed on selected psychiatric disorders. Despite a lot of efforts, stigmatization and discrimination of people with mental disorders is a major problem in all countries. Studies about the effectiveness of anti-stigma activities show contrasting results, some of them indicate that activities were not successful. Research on anti-stigma interventions is essential to understand what might help to reduce stigma and discrimination. © Springer International Publishing Switzerland 2017.

- Stigma is the most powerful obstacle to the development of mental health care. Numerous activities aiming to reduce the stigma of mental illness and the consequent negative discrimination of the mentally ill and their families have been conducted in Europe. Descriptions of many of these activities are not easily available, either because there are no publications that describe them, or because descriptions exist only in local languages. This supplement aims to help in overcoming this imbalance by providing a description of anti-stigma activities in 14 countries in Europe regardless of the language in which they were published and regardless whether they were previously published.

The Adhesion GPCR GPR125 is specifically expressed in the choroid plexus and is upregulated following brain injury
- 2008

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUNDGPR125 belongs to the family of Adhesion G protein-coupled receptors (GPCRs). A single copy of GPR125 was found in many vertebrate genomes. We also identified a Drosophila sequence, DmCG15744, which shares a common ancestor with the entire Group III of Adhesion GPCRs, and also contains Ig, LRR and HBD domains which were observed in mammalian GPR125.RESULTSWe found specific expression of GPR125 in cells of the choroid plexus using in situ hybridization and protein-specific antibodies and combined in situ/immunohistochemistry co-localization using cytokeratin, a marker specific for epithelial cells. Induction of inflammation by LPS did not change GPR125 expression. However, GPR125 expression was transiently increased (almost 2-fold) at 4 h after traumatic brain injury (TBI) followed by a decrease (approximately 4-fold) from 2 days onwards in the choroid plexus as well as increased expression (2-fold) in the hippocampus that was delayed until 1 day after injury.CONCLUSIONThese findings suggest that GPR125 plays a functional role in choroidal and hippocampal response to injury.
